What plugs for a stage 1 saff cosworth.....

Si

 

motorcraft 071s

 

071's will be fine for Stgae 1 Si

 

So fords it is then or maybe tomorrow at the spares day.....what about when running greens cam and 3 bar...?

Si

 

071s are good for 450 bhp

 

As everyone has said Si 071's.If you have no luck at fords i got them here and delivered to your door £17.50

 

CheeRS Stretch I will keep you in mind

Si

 

hope they are good for more than that as well as they are sitting in my engine right now!

 

Their good then porkie?!

Only ones i hear ppl recomend for bigger bhp cossies are champ c57s and NGK 9s!!

 

How good are these plugs.

Fookin cheap Stretch.




Dave.

 

got these ready to go in my car next a full set for less than a £5

beats the £90 i spent on a set of NGK 9

 

So are these platinum type jobbies?!

Bit more info on them would be apreciated

 

Nope just a standerd RST plug

 

really?!??!

and their ok in big bhp cossie engines

 

CheeRS Guys...

Got to be better than NGk 8ES in mine at the mo....

 

I had a bit of a fueling problem because due to time constraints the car had never been mapped down properly. I was EATING through NGK9's and Champions would last 10 mins... and thats NOT a joke one set got me from Scottys place to my house and once the car was turned off it wouldn't restart!

Stu sent me down a set of those 071's and they have been SPOT on and its done over a 1000miles and 2 trackdays on the same set so far. We took em out yesterday and the rocker cover gasket has been pissing oil everywhere in number 4 and it still wouldn't die. PROPER plugs man

The car HAS not run any big boost though so gonna consult Martin Stu and Karl as to whether these plugs are really gonna be upto the job on full boost as the car is getting more powerful as well now

 

Why wouldnt they be in cossies as standard then?! Cos standard cossie plugs melt at stage 3 running any decent boost from what i heard

How much boost u running at the mo in urs lee at mo cos if their ok in urs then cant see a problem with them in a stage 3 cossie!!


Cheers for the update

 

Things have thankfully moved on somewhat in 20yrs

 

Toeknee, Stu reckons they are safe in 500bhp cars! probably going be safe in 600bhp cars as well.... just need someone to find out for sure

 

Well u know what i mean

Just seems strage that a plug made for the RST is better than recomended cossie plugs, and the fact if the RST plugs are better would have thought it would have been made common knowledge cos most ppl say to use the NGKs or C57s over any others in cossies, and i didnt know till this post you could use the 071s without worry of melting the plugs

So another very useful post

 

The 071 is a new Ford plug pal..

 

Has any one got the ford part no for the 071 plugs or do you just ask for 071"s.

 

pp8's will also be fine (std escos big turbo plug)

 

its pretty simple mate

'Stu, pls send me some 071's'

'sure Phill be with you tomorrow'

Job done

P.S best pay for em and tell him your address as well actually

 

071s can handle quite a bit of heat. These came out of a melted YB engine..

The plug on it's own was in the cylinder that was worse off....

 

so do we think they can they handle 650bhp???

 

Personally, id say yes Lee.

However, the unfortunate fact is, theres no easy way to find out for 100% certain without trying em... But hell yeah, i think they will walk it pal

 

How much are they stu?!?!

and for an update on the plug options availible and how well they seem to work, good to hear someone like lee running big bhp able to back them up aswell

 

Would these run in a stage 1 RST also?

 

I'd never use anything other than motorcraft
